Locomotion in VR is hard to be implemented correctly due to the fact that a wrong implementation could cause motion sickness. Most locomotion is implemented by having physical movement from the player or limited movement from the player. I feel that a good way to do this might be allowing the player to lie on a bed and he can move the in-game character by using motion tracking devices with his hand. Hence when the in-game character is moving in VR, the player would not feel too sick as he is resting his head on the bed and can be more relaxed as compared to standing upright to play the game. This might help in reducing motion sickness as the player senses are more relaxed and the locomotion in VR would not be too drastic for the player who is lying on the bed. Furthermore, the player can only move a little while lying on the bed and this might help the player to not overthink the complicated movement introduced by the VR game, allowing the player to feel secure and less likely to feel motion sickness.
